2.6 Submitting Reports from Different Computers

A user certificate and Private/Public Key pair is used to digitally sign and encrypt the submitted 

files, providing security protection for DC FUEL submissions. The certificate and key pair will 

be automatically obtained after the first DC FUEL login. 

The following data is stored into a keystore under your home directory: 

• user ID

• user private key

• user certificate

• creation time

The following file will be created: \<userHome>\ .<userId>-cromerr-keystore.jks where 

<userHome> is a local user home directory (C:\Documents and Settings\myuser) and <userId> is 

your DC FUEL user ID registered with CDX Web (i.e. DCFuelTest01-cromerr-keystore.jks). 

This file is stored on the local drive of the machine that was used to log into DC FUEL to 

complete a submission. While you may submit files from any machine, you will only be able to 

access the copy of records for the submitted documents from the specific machine for a 

submission unless the key file is copied into the same location of another machine. In any case, it 

is recommended that you copy this file to another safe location for backup. 

Reminder: Files may be submitted from any machine however you will only be able to access the copy of 

records for the submitted documents from the specific machine for a submission unless the key file is copied 

into the same location of another machine. Please refer to Section 2.6 for complete details.
